--  euc -extra-lflags="-no-pie" search.ex"  
----------------------------------------------------------------------------------------------------- 
--  euc options 
-- 
--    -build-dir - use the named directory (default is build-[random number]) 
--    -extra-lflags - required on Ubuntu 17.10+ as discussed previously 
--    -makefile - generate a makefile instead of compiling directly  
--                      (will be named [build-dir]/[basename].mak)  
-- 
--   make options 
-- 
--    -j (or --jobs) - use this many simultaneous jobs  
--                        (usually one job per core/thread) 
--    -f (or --file) - use the specified makefile (default is Makefile) 
--    -C (or --directory) - change to the specified directory before doing anything  
-- 
-- This works on Windows or Linux. Only difference is you need to use  
-- mingw32-make instead of just make on Windows.

3. DOES euc work with the latest version of Linux Mint?

Which version of Linux Mint are you using now, Irv?

Anyone else using a recent version Linux Distro which runs euc up to snuff?

Here's something you can try, since most of the discussion on the web involves -ffast-math:

euc -keep -build-dir build -extra-lflags="-no-pie" -makefile hello.ex

Open the /build/hello.mak file

 
CC     = gcc 
CFLAGS =  -fomit-frame-pointer -c -w -fsigned-char -O2 -m64 -I/usr/local/include -ffast-math 
LINKER = gcc 
LFLAGS =  $(RUNTIME_LIBRARY) -m64 -ldl -lm -lpthread -no-pie 
... 

Remove the -ffast-math from the end of the 2nd line and save it. Then run make (specify no. of cores with -j, or leave it out)

make -j8 -f hello.mak -C build

On my Linux version, test program compiles correctly with or without the -ffast-math.

I've read what I could find, and I haven't found a proposed solution that I understand how to implement. What does "link with -lm" mean? And how to do it?

Edit 1: also, some change I made recently in EuGTK causes it to seg-fault, so I rolled it back to Oct. 2019

I haven't compiled a program in a long time. Finding the cause of the seg-fault isn't something that interests me very much, since I discovered that binding vs. compiling shows very little difference even on a lowly Raspberry Pi 3.

Edit 2: comparing bear.ex - a rather large program that includes several libraries:

Compiled version - load and display window and controls, and 2 files, ready for input - .6049 sec Interpreted version- .6845 sec Bound version - .6197 sec.

I don't think 8/100ths of a second is going to make a lot of difference :)
